 ## Set up
 
-You can run Kubernetes via Minikube or K3s. After the installation (we suggest
-you Minikube in this case) you have to set up the environment:
+You can run Kubernetes via Minikube or something else. For this project we
+used KinD. If you install KinD do not forget to also install a Load Balancer for
+Kubernetes: [Cloud Provider
+KinD](https://kind.sigs.k8s.io/docs/user/loadbalancer/) is what we used.
+
+Now, you can proceed to set up some environment variables:
 
 - `JWT_SECRET`: the base64 version of the secret used for JWT tokens.
 - `EXPO_ACCESS_TOKEN`: the base64 version of the [Expo](https://expo.dev) access token.
 - `UNREALSPEECH_TOKEN`: the base64 version of the [Unrealspeech](https://unrealspeech.com/) access token.
 - `RUST_LOG`: level of Rust logging
-- `AUDIO_PATH`: path for the audio folder
-- `ALLOWED_HOST`: host for the app
 
-After that just run
+Meanwhile the followings are setted up by default.
+
+- `AUDIO_PATH`: "./assets"
+- `ALLOWED_HOST`: "0.0.0.0:8000"
+
+After that just run the `run.sh` script.
 
 ```sh
 ./run.sh apply
 ```
+
+After that, you'll be able to see what the external IP for the load balancer is.
+
+```
+$ k get svc
+NAME               TYPE           CLUSTER-IP     EXTERNAL-IP   PORT(S)        AGE
+cas-service        LoadBalancer   10.96.25.163   172.18.0.3    80:30358/TCP   11m
+```
+
+For the IP above you can test if it works by a HTTP request.
+
+```
+$ curl -X POST http://172.18.0.3/graphql \
+-H "Content-Type: application/json" \
+-d '{
+  "query": "mutation Login($input: LoginCredentials!) { login(input: $input) { accessToken tokenType userId } }",
+  "variables": {
+    "input": {
+      "email": "info@cas-4.github",
+      "password": "mysuperpassword"
+    }
+  }
+}'
+```
+
+If you receive a network error you just need to wait until the
+`cloud-provider-kind` works.
